The mechanism 'for applying the fastening means to the body of the envelope and I which co-operateswith the under face of the supporting bed,-w1th which mechanism our invention is chiefly concerned, consists as her'etoforestated of elements somewhat similar to those employed in connection with the mechanism co-operating with the upper anvil. There is provided a reciprocating plunger 57 which carries a spring-pressed pin 58 which plun er is ada' ted to be reci rocated through the medium, of .the crank 59 and connecting links 60-61; A st-ack'of washers or disks '62 are mounted upon a rod 63; but instead of being fed gravity,

asfiin the case of the upperwashers, it is necessary to provide a positive means for.

feeding these disks upwardly on this rod.

the weight65 which is conne cted to this car riag'e through the. i i-iedi-umbra rope 66. In

This, is accomplished by means of a carriage 64 which engages the lowermost-disks and is forced upwardly by power derived from this manner there is a constant upward pressure on the disks 'so that the upper'disk is .c'iprocating slide 67. (See Fig. 6.);

forced into position to be engaged by the ren V This slide is provided with'fa shoulder 68- so' that astlie slide is reciproc-ated it engages with the top washer and feeds thefsame laterally ofi' thetop of thestack. .This. slide is adapt ed to'vbe reciprocatetd by the operation of the cam 39 mounted on the shaft 26 and rocking armel to the outer end of which the arm 69 is secured, theupp'er end of this arm be ingsecured to a crank 7 0 on one end of a shaft 71. To the opposite end of this. shaft a crank 72 is connected, the opposite end of WlllCl] is connect-ed to'the depending lug 73 on the'shde 67, This construction issuch V that'as the cam 39 rotates, the slide 67 is re 7 I Vcipr'ocatedso'as to feed the upper disk or washer in the stack62 forwardly intoa position to be engaged by the springpin 58 in the end o'fthe reciprocatingplunger 57 In order to properly.support the washer when it is thus fed ofifthetop of the stack, it is 1iecessary-to provide "special supporting 3 means such'as are shown in detail in Figs.

4 "through 7 This consists essentially of a supporting memben74 mounted upon the slide 67 which supporting member is pro videdj fwithia forwardly extending portion 1 7 5' having'a' pairo f downwardly curved supportingarms .76which are in aposition to receive andhold the washer. j The end ofthe f supporting member 7 gt fis cutaway at 77 to permit the yielding pin '58 7 toehgage with a washersupported by the slide'. This sup porting slide 74: is "connected to the main slide 67 by a spring. connection78 and the main slide 67 is provided with anjupwardly projecting portion 79 which, upon the forward movement of the slide 67, is adapted 1 to engage the forward endof the supporting slide 74; and force the same outwardly into the position shown in Fig. 4. That'is, in

operation the slideis normally in the posisition shown in Figs. 5 and"6,'but as the slide 67'is forced outwardly it picks the disk off the top of the; stack and moves the saine'on 'to the supporting arins76 and then the slide" 67 and supporting member 74; move together until'this disk is: carried into a position immediately over, the spring press ed pin 58. Then as this pin moyes upwaridly, the washer is slipped over theend ofthe pin and then the slide 67 is retracted and the spring 78 pulls the supporting member 7a backwardly so that this supporting member is moved out of the path ofithe reciprocating plunger- 57.,
